Icom Ic-m423. The IC-M423 is Icoms next generation VHF/DSC. Together with its optional HM-195 COMMANDMIC, the IC-M423 benefits from a new user interface which makes driving this Icom fixed mount incredibly simple. A compact radio that will fit easily into any console, size does not mean a loss of performance. Boasting and packing a proverbial punch with its audio of 10W from its loud speaker makes sure you will clearly hear calls. The IC-M423 also has a Public Address & Fog Horn function so when attached to a hailer horn will expand the usefulness of this new radio.Active Noise Cancelling Technology:The built-in bidirectional active noise canceller reduces background noise to up to 90% and improves both your transmitted voice and incoming calls. This could be really essential for you, making you heard when you really need to, such as when the weather conditions are poor or if engines are running.New Marine Family Common User Interface:The IC-M423 has an easy to use interface that will be incorporated into future Icom radios. The common Marine Family User Interface provides simple operation for the boat owner. A rotary selector, directional keypad provides intuitive operation. The high definition dot matrix display allows all information to be clearly viewed.10W Loud Audio, Public Address and Foghorn;The IC-M423 has a built-in 10W amplifier that increases the audio output from an additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, and the foghorn can also be emitted from the additional external speaker.Built-in Class D DSC:The built-in DSC watch function monitors Ch. 70 (DSC channel) activity, even while you are receiving another channel. DSC functions include: distress, individual, group, all ships, urgency, safety, position request/report*, polling request* and DSC test calls.*Available upon request.Common GPS/NAV Interface:When connected to an external GPS receiver, current position and time are shown on the IC-M423s display. When receiving position information from another vessel, the IC-M423 can transfer it to a navigational device via NMEA 0183 connectivity.Compatible with Icom MA-500TR Class B AIS Transponder:The IC-M423 can be integrated with the Icoms MA-500TR Class B AIS Transponder allowing you to transmit DSC individual calls to a selected vessel instantly without manual MMSI entry; very handy if you are waiting to contact vessels on the AIS screen, an essential safety feature in an emergency.IPX7 Submersible Protection (1.0m depth for 30 minutes:The IC-M423 withstands submersion in up to 1.0m depth of water for 30 minutes. It is equivalent to the IPX7 standard. Features:- AquaQuake draining function- Dual/tri-watch function for monitoring Ch.16 and/or call channel- Priority and normal scan- Built-in attenuator for local communication- Black and white versions available.Specifications: – Active Noise Cancelling Technology- New Marine Family Common User Interface- High Definition Dot Matrix Display- 10W Loud Audio, Public Address and Foghorn Capability- Built-in Class D DSC- Newly designed optional HM-195 COMMANDMIC4- Compatible with Icom MA-500TR Class B AIS Transponder- Available in Black or white

Icom Ic-m35. The buoyant IC-M35 is the latest in Icoms line-up of rugged marine handheld transceivers and comes with a great new feature that all boat users will love – Clear Audio Boost!Clear voice boost (Clear Voice + Voice Boost)In marine environments there are many sources of noise that can affect the quality of your communications, such as engine noise, roar of the waves etc. The IC-M35 automatically adjusts the outgoing voice and the incoming audio to compensate for the ambient noise level: whether youre in a loud environment or in a quiet area, the IC-M35 ensures your radio conversation is sent and received as clearly as possible.LOUD button;When you need an instant boost in the volume, a simple push of the LOUD button gives you full volume immediately. In addition, holding the LOUD button mutes the audio output.Noise cancelling microphone:The sub-microphone on the rear panel inverts phase and cancels out ambient noise from the main microphone. As a result, the IC-M35 reduces the affect of background noise (particularly trebly noise) from the transmitted signal and makes it easier to catch voice communication.Automatic volume adjustment;In a high noise environment, the sub-microphone detects the ambient noise and the IC-M35 automatically increases the volume output to suit the surrounding environment.700mW audio output:The IC-M35 employs a bridge-tied load (BTL) audio amplifier to increase the audio output power. The internal speaker delivers a loud 700mW (typical) audio output with clear sound even in noisy environments.And yes, it floats too!:Just like the IC-M33, the IC-M35 floats in the water. If the radio is dropped over the side, it will come to the surface so you can retrieve it. As the radio has a rugged, waterproof body, it will keep on working even after it has been submerged.* 1m depth for 30 minutes, equivalent to IPX7. Please note that the IC-M35 is not designed to be used under the water.6W RF output with low power consumption:Although the IC-M35 delivers a high 6W RF output and 700mW audio output, its current saving circuit offers 8 hours* of operating time with the supplied 980mAh Lithium-Ion battery pack.* Typical operation with Tx (Hi): Rx: standby=5:5:90Large buttons and slim dimensions:The IC-M35 has large, easy-to-operate buttons that provides intuitive operation. A slender design body makes it extremely natural to handle.Easy to see LCD with large channel indication:The IC-M35 has an easy to see large LCD (32 x 16 mm) with a clear 2-digit channel number indication. The LCD is laid out on the top of the front panel not to be covered with your hand. LCD and key backlighting is standard for night time operation.Features:- Keypad backlighting- Waterproof construction equivalent to IPX7 (1m depth for 30 minutes)- Optional battery case for use with alkaline cells (The IC-M35 floats flat when this battery case is connected)- Dual/Tri-watch functions- 4-step battery life indicator- Auto scan function- Instant access to Ch 16 or programmable call channel- Soft flexible antenna supplied- Quick channel selection with Favourite channel function- AquaQuake draining functionSpecifications: – Loud button for instant Maximum volume boost- Noise cancelling microphone- Automatic volume adjustment- Floats in the water- IPX7 waterproof protection (1m depth for 30 minutes)- 6W RF output and 700mW audio- Large buttons and slim design- Easy to see LCD with large channel indication- Optional speaker-microphone, HM-165
